Izzie has always been curvy, but since Christmas she has gained eight pounds, and nothing seems to fit anymore. In an attempt to lose weight, Izzie tries everything: one diet after another, a punishing exercise program, and every bit of conflicting advice anyone can give her.

Her constant worrying about her weight causes her to lose her confidence, and she stops appreciating the things in her life that are special -- her supportive friends, the fact that she has been selected for a TV teen panel, and a cute boy at the TV studio who seems to like her just the way she is.
